NVME-SNDK-CLEAR-A(1)

💅 nvme-sndk-clear-assert-dump(1) — the NVMe Manual, bestie edition

okay so you found the nvme-sndk-clear-assert-dump page in the NVMe manual and you're like "what is this" — don't worry, I got you 🫶 it's a tiny little vendor command and it's honestly not that deep, but let's do it properly.

---

✨ NAME ✨

nvme-sndk-clear-assert-dump — clears the assert dump (if present). that's it. that's the whole job 💅

---

🌸 SYNOPSIS 🌸

nvme [<global-options>] sndk clear-assert-dump <device>

---

🦋 DESCRIPTION 🦋

so for the NVMe device you hand it, this bad boy sends the sndk vendor unique clear assert dump command. iconic, niche, very "you had to be there" energy 🔥

the <device> parameter is mandatory — no device, no vibes — and it has to be the NVMe character device (ex: /dev/nvme0). like, actually the char device, not whatever random thing you found in /dev 👀

🚨 real talk: this will only work on Sandisk devices supporting this feature. if your device doesn't support it, the command simply will not be executed. no error drama, it just won't run, periodt.

---

🎀 OPTIONS 🎀

None 😌 this subcommand has zero options of its own. the whole personality is in the global options below.

---

👑 GLOBAL OPTIONS 👑

these are all defined at the top-level nvme command and they're available to this subcommand too. so like, they're the shared friend group of options 💜

• --dry-run — prints the command that would be executed, but doesn't actually execute it. a little "look but don't touch" moment 🙈
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — turns off retry logic on transient errors.
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. only one output format at a time, bestie, pick a lane ✨
• --output-format-version=<version> — selects the output format version. version 1 uses the original field naming, while version 2 (the default) provides more consistent and script-friendly field names. any other version? rejected 💀
• --quiet — suppresses informational messages. errors are still reported, and --quiet cancels any --verbose for the library log level. so it's a "shhh" that also overrules the yapper 🤐
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command in milliseconds. infinite or -1 waits without a time limit (0xffffffff). so yeah, you can wait forever, choose wisely 😭
• -v, --verbose — increases the level of detail in the output. may be specified multiple times to further increase verbosity. stack it like a combo 🔥

oh and — these options can also be set as machine-wide defaults in nvme-cli.conf(5). a command-line flag always overrides the file. file says one thing, flag says another, flag wins, no cap 🫶

⭐ EXAMPLES ⭐

• clears the assert dump (if present):

# nvme sndk clear-assert-dump /dev/nvme0

like, that's the whole example. do it. slay. 💖

and that's the page, bestie! this whole thing lives in the NVMe manual, dated 10/30/2026, source/version NVME-SNDK-CLEAR-A(1) — so go forth, clear that assert dump (if present), and remember: <device> is mandatory, Sandisk only, no options, still iconic 🎀💅🦋
